Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621408, here are decompositions:

11 + 33621397 = 33621408
19 + 33621389 = 33621408
47 + 33621361 = 33621408
97 + 33621311 = 33621408
109 + 33621299 = 33621408
157 + 33621251 = 33621408
239 + 33621169 = 33621408
409 + 33620999 = 33621408

Showing the first eight; more decompositions exist.
